HARROW.

SPECIFICATION forming part of Letters Patent No. 532,332, dated January8, 1895'. Application filed January 15, 1894. Serial No. 496,927- (Nomodel.)

holder which laps outside of as well as fits within the channeled beam.

The invention has for further objects other improvements and consists inthe novel constructions and combinations of parts as will be hereinafterdescribed and pointed out in the claim.

In the drawingsFigure 1 is a face view. Fig. 2 is a top plan View; Fig.3, a sectional View of a harrow beam provided with my improvements, andFig. 4 is a detail view of the holder.

The harrow frame is formed with beams A of channeled or double-flangedmetal as shown and the frame may be of any desired style, the beamsbeing arranged with their flanges one above the other and the hollow ofthe beam opening laterally. This beam has bolt holes a atintervals forthe bolt B which secures the tooth holder. This bolt connects with thebody 0 of the tooth holder D in any suitable manner, passes through thehole a and is suitably secured.

The tooth holder D is formed With the body portion 0 which fits betweenthe flanges of the beam Band with the lugs or ears E which lap over andfit against the outer sides of the flanges A of the beam. These lugs orcars are preferably four in number, two above and two below, one at eachside of the tooth sea-t F. In fact these ears are in the nature ofextensions of the clamp like cross pieces Gv against the tooth fromcausing the holder to' force the flanges of the beam apart and thusloosen the fit of the holder between said flanges. This results fromproviding the tooth holder with the overlapping portions or ears fittingoutside said flanges as shown.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

As a new and improved article of manufacture, the harrow tooth holderherein de scribed composed of the body portion, the upper and lowerlaterally projecting clamps which fit around the tooth, the inner endsof the side arms of said clamps being extended or prolonged over thebody, forming flange.

like portions, said flange like portions being separated from the bodyto form a seat for the rail plates and separated from each other toavoid any obstruction to clamping the tooth against the rail,allsubstantially as and for the purposes set forth.
